Described fixed part is that a below is fixed on bottom seat cushions, and top is fixedly connected with the L shape bend pipe of one " recessed " shape holder, and below is provided with and the screwed hole be fixedly connected with below seat cushions and pad; Be provided with positive stop inside it, rotate in the scope of angle 0-90 degree around the pin joint of fixed part for restraint portion.
Described movable part is by the Connection Block be fixed on backrest and one end and Connection Block is hinged, the other end and the hinged movable brace rod of holder and form in the outside of Connection Block and holder and the two hinged positioning supporting rod, positioning supporting rod be arranged so that Connection Block can remain vertical in movable part rotation process, thus make backrest keep with seat cushion perpendicular.
In order to make the backrest of this seat disseat pad front end distance go for more crowd, described holder two side is provided with gear hole; Described positioning supporting rod is provided with a through hole in the position corresponding with gear hole, a positioning ball is placed in through hole, a compressing tablet is established outside described positioning supporting rod, described compressing tablet side is fixed on positioning supporting rod, opposite side is provided with through hole, described through hole is pressed on positioning ball accordingly, and its through hole radius is less than the diameter of positioning ball.
In use, described positioning ball is between holder two side, positioning supporting rod and compressing tablet, and when positioning ball enters gear hole, compressing tablet is in positioning states; When positioning supporting rod leaves gear hole, positioning supporting rod is in non-locating state.
The beneficial effects of the utility model are: 1, the design of travel(l)ing rest makes user can come adjusting seat backrest and the distance between oneself according to the custom of oneself, different physique and height, not only make user more comfortable, also help the correct sitting posture cultivating child, avoid damaging vertebra; 2, gear hole be arranged so that backrest can have multiple gear to regulate, the scope of application is more extensive; 3, positive stop be arranged so that the movable part of travel(l)ing rest rotates in the scope that angle is 0-90 degree around fixed part, prevent apart from excessive or too smallly cause spinal cord injury to user.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the movable part of travel(l)ing rest and fixed part are in mutual plumbness;
Fig. 3 is the structural representation that the movable part of travel(l)ing rest and fixed part are in level.
Detailed description of the invention
As shown in Figure 1, the backrest adjustable seat that the utility model will be protected comprises the travel(l)ing rest 3 that seat cushion 1, backrest 2 and one end are fixed on bottom seat cushion 1, the other end is fixed on backrest 2 and forms; Described travel(l)ing rest 3 comprises fixed part 31, forms with fixed part movable part 32 that is hinged, that can rotate in the scope of angle [alpha] around fixed part.
Described fixed part 31 is fixed on bottom seat cushions for below, top is fixedly connected with the L shape bend pipe of one " recessed " shape holder 311, be provided with below it and the screwed hole be fixedly connected with below seat cushions and pad, inner side is provided with positive stop 311-1, rotates around fixed part for restraint portion in the scope of angle [alpha]=0-90 degree.
In order to reach the front and back of adjusting seat and upper and lower distance, described movable part 32 is by the Connection Block 321 be fixed on backrest 2 and one end and Connection Block is hinged, the other end and the hinged movable brace rod 322 of holder and form in the outside of Connection Block and holder and positioning supporting rod 323 that the two is hinged, strut be arranged so that Connection Block can remain vertical in movable part rotation process, thus make backrest keep with seat cushion perpendicular.
In order to make the backrest of this seat disseat pad front end distance go for more crowd, described holder 311 two side is provided with gear hole 311-2; Described positioning supporting rod 323 is provided with a through hole in the position corresponding with gear hole, a positioning ball 324 is placed in through hole, a compressing tablet 325 is established outside described positioning supporting rod 323, described compressing tablet 325 side is fixed on positioning supporting rod 323, opposite side is provided with the boss of through hole, described through hole is pressed on positioning ball 324 accordingly, and its through hole radius is less than the diameter of positioning ball 324.
In use, described positioning ball is between holder 311 two side, positioning supporting rod 323 and compressing tablet 325, and when positioning ball 324 enters gear hole 311-2, compressing tablet is in positioning states, when positioning ball 324 leaves gear hole 311-2, compressing tablet is in non-locating state.
As shown in Figures 2 and 3; the operation principle of the utility model a kind of backrest adjustable seat required for protection is: described travel(l)ing rest 3 one extreme positions are Fig. 2 state; now, described backrest 2 seat cushion 1 front end that disseats is nearest, and it is highly also minimum.Positive stop 311-1 inside holder 311 makes the movable brace rod 322 of movable part be in level; As user thinks now backrest 2 and disseats seat cushion 1 front end hypotelorism, then can regulate backrest 2, the movable part 32 of travel(l)ing rest 3 is rotated around fixed part 31, when described positioning ball 324 enters the first gear hole, positioning supporting rod 323 is in impaction state and positioning states, backrest is located, and from the state diagram of Fig. 2 to the first gear hole process, owing to there being the existence of positioning ball 324, make to there is gap between floor and holder, and by locking ball joint, rub greatly less.
If desired regulate backrest to next gear, then need to exert oneself slightly, make positioning ball 324 leave gear hole, continue to slide on the lateral wall of holder 311, when movable part makes positioning ball 324 enter next gear hole around fixed part motion, backrest is located further.
As shown in Figure 3, when the movable part 32 of travel(l)ing rest moves to vertical position, this position is another extreme position of described backrest 2, now, positive stop 311-1 inside described holder 311 limits movable part to be continued to rotate around holder 311, under this state status, seat by 2 back of the body block distance seat cushion 1 farthest, is namely in same plane with the outermost of seat cushion 1.
In travel(l)ing rest of the present utility model, the movable part 32 being arranged so that travel(l)ing rest 3 of positive stop 311-1 rotates in the scope that angle is 0-90 degree around fixed part 31, prevents apart from excessive or too smallly cause spinal cord injury to user; The design of positioning ball makes to greatly reduce friction during relative motion between movable part 32 and fixed part 31, and the cooperation of gear hole 311-2 and locking ball 324 makes backrest have multiple gear to regulate, thus user can come adjusting seat backrest 2 and the distance between oneself according to the custom of oneself, different physique and height, make the scope of application of seat more extensive, not only make user more comfortable, also help the correct sitting posture cultivating child, avoid damaging vertebra.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to spirit institute's apparent change of extending out of the present utility model or change and are still among protection domain of the present utility model.
